What's the best way to power my laptop in the car?

Found 7th Nov 2007
I have a Toshiba Portege 3500 and would like to power it in the car for a long journey, is there a cigarette lighter adaptor available for it or should I get an invertor to give me 240v and then plug the normal plug into that?

Any help appreciated!

Go for an invertor. That way you can use it for other things as well, and it'll most likely be cheaper.

Nice one Shengis, any recommendations? Are they ok for long term use? Is there a power rating I should be looking for? ie at least 300W???

I was in Homebase yesterday & saw exactly what you need! Can't remember what it was called, though, nor the cost - too busy looking at other things:giggle: If there's a homebase near you it could be worth a look (amongst the extension cables / power leads); also, if Homebase are selling it then others like B&Q will most probably be as well.

Not sure. I think mines a weedy 150w model (cos i'm tight) but it's always better to overspecify. 300w should be more than enough for a laptop. Just remember though that you should never run one with the engine turned off. I stopped for petrol one time and forgot to switch it off and had a hell of a time restarting the car:giggle:

Good tip, I wouldn't leave it on usually but might forget to turn it off when filling up!

Looked at getting one from ebay before so will look there again, any other recommendations of where to get one from?

Did it look like this?

amazon.co.uk/Bel…8-2

Think this is the one I'm gonna go with. It's 300W and I have Amazon vouchers to burn up so this will help!

I suppose most places sell them now. Ebay is probably the cheapest but Maplin do the odd offer on them. Just remembered why I bought the low power version. It's because the high powered ones need a direct connection to the battery using croc clips, the cigarette lighter socket wiring isn't meaty enough to carry the current for long periods:thumbsup:

It was a similar concept (cig lighter at one end, plug at the other), but it looked more like a 4-plug extension.

As you have the vouchers, & the Belkin does the job, I'd go for it:thumbsup:

That one's fine isn't it? 300w and has a cirarette lighter connection so I assume no direct connection to the battery needed?

Yeah that's fine. A lappy doesn't draw too much current so won't be a problem. It should come with a set of crocs as well in case you want to use it at it's max:thumbsup:

And cirarette is spelt cigarette :giggle:

:lol:

I blame my keyboard, it's possessed.

Ive got a similar thing from Halfords, I bought a 'cheaper' one from Ebay first, but it was an import and every time I drove over a slight bump, it dislodged the connection & the kids had to restart their playstation game! Went to Halfords, paid around £30 for a middle range one but with built in auto turn off for protecting the battery etc, and it is great & saves the need for adapters for mobiles etc too.
